I covered the basics of JavaScript – targeted to a Computer Science major (in the case of the students at NU, they learn Scheme and Java so I emphasized the subject matter to that audience). I did a fast run-through of the whole language, covering the main points, and move on to a quick inspection of jQuery and the DOM – closing with some Q&A. The subject matter of JavaScript 2 (and 1.6-1.8) came up a couple times so discussion of that was interspersed throughout. There were a bunch of jQuery users in the audience and it was great to get to hear their feedback.
